Last week I wrote an article for one of our sister sites, GadgeTell, on ways Barnes & Noble could remain relevant with the Nook line. While I stand by everything I wrote in that article, I missed an important point.

One of the reasons I stay with Amazon and my Kindle Touch is because of the “Send To Kindle” feature. Send to Kindle allows you to treat personal documents the same as Amazon content, including syncing between multiple devices.

It’s easy to use. After downloading and installing the app, simply right-click on a document, and Send to Kindle will be one of your options. The following window will pop up and you can choose which device(s) you want to send to.

See the “Archive document in your Kindle Library” box? Check that, and Amazon will store it in the cloud, and sync your location between multiple devices.

I like to read on my Touch, my iPad and my iPhone, depending on where I am. I rely on the ability to maintain my location on multiple devices. Barnes and Noble and Kobo both sync their content to multiple devices, but not side-loaded personal content. If you’re like me and read books from multiple sources, on multiple devices, you’ll value that ability from Amazon.

When I go into my local Best Buy, I look at the Nook HD and the adorable Kobo mini. I start to think that maybe my budget could afford one more gadget and reach for my wallet. Then I think about manually syncing locations with my iPad and move on to eye the Kindle Fires.

It’s so simple. The other booksellers could implement it quickly. Why don’t they? Is it really better to complain about Amazon instead of making changes to compete effectively?
